Be it known that I HOMER MonRis, a citizen of the United States,residing at Hermosa Beach, in the county of Los Angeles, State ofCalifornia,-have invented new and useful Improven'ients in FlushingApparat-us, of which the following is a specification.

My invention relates primarily to apparatus for flushingwater closetsand is illustrated and described herein as applied to that purpose,although the apparatus may be used for other purposes, and the objectthereof is to provide a device of Simple construction and compact formin which the controlling valve is manually started to coinmence theoperation and is held open automaticall-y until the flushing iscompleted when the controlling valve will return to-its I accomplishthis object by the apparatus described herein and illustrated in theaccompanying drawii'igs in which z- Figure l is a sectional frontelevation ofthe flushing apparatus. Fig. 2 is a side elevation of thecontrolling valve partly in secgtionland showing it connected to thecloset )ow In the drawings 5 is the supply pipe which is connected to asource of water supply under pressure of a suiiicient head for flushingpurposes. sually this will be the city water This pipe is provided witha regulating cock 6 and is connected to and opens into an air chamber 7.I have shown a sup ply pipe connected to the air chamber at the bottom,but the connection may be made at the top, or at any intermediate pointbetween the top. and bottom, providing the supply pipe passes a point ona level with or below the bottom of the air chamber. Leading from thebottom of the air chamber is a pipe 8 which is connected to the casing 9of valve chamber 10. The top of valve chamber casing is preferablyclosed by a plug 11 which is provided with a down-.

wardly projecting flan e 12 which is exteriorly threaded. On tns flangeis screwed a tubular regulator 13 which can be screwed up or downupon-the flange to regulatethe distance between the regulator and valveseat 14 which is formed on the casing 9 at the bottom of the valvechamber, whereby the volume of water flowing through the valve chambercan be regulated. Below the valve seat, casing 9 is reduced in size andis pro- Specificat'wn of Letters Patent. Pg icentefi Aug, Applicationfiled March 22, 1907 Serial No. 363,978.

vided with a boss 15 through which projects the valve ope-rating shaft16, the innercnd of which forms a crank or eccentric 17. On the outerend of shaft 16 is the operating handle or lever 18. \Vith-in the bossand connected thereto and surrounding shaft 16 is a stufiing box 19 tomake the joint around the shaft water-tight. On valve seat 14 is valve20 which is secured upon the top of valve stem 21 in any suitablemanner. This valve when raised off its seat passes up into regulator13,. This regulator forms a cupshaped receptacle in which the valve,when raised, is held by the flow of the water until the pressure intheair chamber is relieved.

The lower end of the valve stem is bifurcated and the furcations 22thereof straddle crank 17. To the lower end of the casing f, is securedflushing pipe 23 which leads to and is connected with the closet .bowl2A. I prefer to place the air chamber-and the valve casing within thepartition wall and to cover the opening necessary for the insertion atthese parts by a removable plate 25 which can be taken oil when it isdesired to remove the parts for repair. A slip coupling 26 as, rac

permits of the disconnection of the valve casing from the flush pipe,and a union '27 on pipe 8 permits the removal of the valve casingwithout interfering with the an chamber. By unscrewing plug llthe valvecan be removed from the casing and replaced after being repaired. Wheninstalling this apparatus the air chamber would preferably be connectedup when the plumbing of the building was roughed in, althouglri it couldbe installed afterward.

here there are closets on the same floor on the opposite sides of thepartition the pipe 8 may be provided with a branch which would lead toanother valve casing containing a valve and other connections similar tothose described herein. It will be understood that the air chamber is ofsuitcient capacity to hold the desired quantity of water for flushingpurposes, but that it does not require a capacity suilicient to hold allof the water required for a single flushing of, the closet, as a certainamount of supply will be' furnished through pipe 5 during the flushingoperation.

With my flushing apparatus in. position and properly connected, when itis desired to flush the closet, the operating handle would be turned tothrow the valve into the regulator, when the water would flow downwardlyaround the bottom of the regulater passing on through the using and"flush pipe into the bowl in the usual manner.

The fiow of the water under t lieved, when the suction of the water passing through the lower part of the valve casing and the weight ofth-cvalve will cause the valve to automatically seat itself. The supply ofwater passing through cock t3 must be less than the amount of waterwhich can be'discharged through the valve cham-. her, and the time thatitwill take for the valve to reseatitselthwill be regulated, first bythe quantity ofwater which accumulates in the air chamber, and secondlyby the amount of water that 'is'permitted to flow into the air chamberduring the process of 2C flushing. It will be observed that it thequantity of water entering the air chamber through pipe 5 was equal tothe quantity of water discharged through the valve chamber when the.valve wasa'aised into the regulator it would remain in that position aslong as the waterilowed, and it isnecessary there fore that the supplyof water entering the air chamber shall be less than that dischargedthrough thevalve chamber. It will also be observed that ,thevolume andvelocityjot' flow of'water passing through the valve chamber, iscontrolled by the regulator 1 sothat my apparatus canjbe used upon anywater systemwhether the pressure be high or lowg If the pressure ishigln the distance between the bottom ofthe regulator and valvel seatwould] be inuch'less than if the pressure were low, the distance beingregulatedfin accordance with'the @prcsstu'e. It 40 will'also be observedthat after the valve is ,seated the \vaterpressure of the main causesthe wate rto accumulate in the air chamber until theairis compressed toa point equal to theljvater pressure, and that when the 15 valveunseated this air pressure is exerted onthe whole body of the water inthe air chamber-and that during the fiushingprocess a fee nquantity.ofwater-fiows through the valve is reseate'd, iltwill also beob-, served, that as, longa-the air pressure in the the supply;'pipeganda ds in. flushing until hamber ended by, the inflow; of water; from theservice pipezvisi sufiicfient'to dis-1 2h egv a ter through itheflval vechamber velqcitya utl'icieutj-to-zhold the, valve he: v regulatorqtheafiushin I ne regulator ,5 will hold the valve up in. the regulator untilthe air pressure in the air chamber is iei weight at the valve and thestem and the g proceeds;

but that as soon as the velocity of the water is not sufficient. to holdthe valve in the regulator it will automatically return to its seat. itwill also be observed that in causing the valve to reseat itself therewillbe the suction of the water below. \Vithout the use of the regulatorthe valve would remain uuscated the same time whether t e pressure washigh or low and would therefore be an misatislactory tl]')[):l1'tltllSas I have found from my practice] experiments;
